77ENGLISHPipe insulationInsulating the refrigerant pipes and branch jointsf Check for gas leakage before completing (the hose and pipe insulation) and if there is no sign of leakage, make sure toinsulate the pipes and hoses.f Use EPDM material insulator that meets the following conditions.Test item Unit StandardDensity g/cm3 0.048~0.096Dimensional change rate by heat % Below -5Absorption rate g/cm3 Below 0.005Thermal conduction rate W/m·K Below 0.037Moisture transpiration factor ng/(m2·s·Pa) Below 15Moisture transpiration grade g/(m2·24h) Below 15Formaldehyde dispersion mg/L There should be noneOxygen rate % Over 25Selecting the refrigerant pipe insulatorf Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.f The standard condition is; temperature at 30°C, humidity less than 85%. If case if the humidity is higher, you mustincrease the size by one grade as stated in below table.Pipe Outer diameterInsulator (Cooling, Heating)RemarksGeneral[ 30ºC (86ºF), 85% ]High humidity[ 30ºC (86ºF), over 85% ]EPDM, NBRmm inch mm inch mm inchLiquid pipe 6.35~9.52 1/4~3/8 9 3/8 9 3/8Heating resistingtemperature over120°C(248°F)12.7~50.8 1/2~2 13 1/2 13 1/2Gas pipe6.35 1/4 13 1/2 19 3/49.52~25.4 3/8~1 19 3/4 25 128.58~44.45 1 1/8~1 3/4 19 3/4 32 1 1/450.8 2 25 1 38 1 1/2❋ When installing insulation in places and conditions below, use the same insulation that is used for high humidityconditions.- High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building iscovered by earth and sand.)- Restaurant ceiling, sauna, swimming pool etc.- The ceiling frequently exposed to moisture and cooling is not covered. (e.g. The pipe installed at a corridor of adormitory and studio or near an exit that opens and closes frequently.”)- The place where the pipe is installed is highly humid due to the lack of ventilation system.k}tGzG⴬㨰䛙G㐘㞬ὤGptluki]_TWZ_XYhTW_UGGG^^ YWX_TW]TXXGGG㝘䟸G[a[_a[^
